Industry Activities • Licensing risk is a key issue for the industry to move forward with actual plant orders • Previously separate construction and operating licenses were required • No certainty provided by this process • Many physical changes were required prior to receipt of operating licenses • Costs increased due to schedule delays and rework required • Industry has adopted new process which results in combined construction and operating license
Pre-Construction Early Site Permit Construction Verification Combined License Review, Hearing, and Decision Verification of Regulations with ITAAC Reactor Operation Decision Optional Pre-Application Review Standard Design Certification • Licensing decisions finalized before major construction begins • Inspections to verify construction • Limited work may be authorized before license is issued New page 23 New Licensing Process provides regulatory certainty
Industry Activities • Industry has adopted several standard designs • Westinghouse AP 1000 (design certified 1/2006) • General Electric ESBWR • General Electric ABWR (design certified 5/1997) • Areva US EPR • Mitsubishi US APWR
New Technology - Advanced Reactor Characteristics • Safety • Use of passive safety systems • Gravity flow and natural circulation designs for cooling • Design • Reduced number of components and bulk commodities • Eliminate pumps and valves previously needed • Use digital controls and fiber optic cables • Procurement • Standardization of components based on NRC approved design
Fewer Components Reduce Plant Costs 45% Less Seismic Building Volume 70% Less Cable 50% Fewer Valves 35% Fewer Pumps 80% Less Pipe Confidential and Proprietary
New Technology - Advanced Reactor Characteristics • Construction • Extensive use of modular construction improves quality and reduces on-site construction requirements • Digital controls reduce size and complexity of systems • Shorter construction schedule • Operation and Maintenance • Use of proven systems and components • Man-machine interface advancements • Fewer systems to maintain and test reduces staff
Smaller and Simpler than Current Plants Sizewell B AP1000 74147A
Economics • What makes Nuclear attractive? • Fuel volatility, both gas and coal, is a major concern • Fuel transport and supplies are showing signs of capacity constraints • Environmental compliance measures are increasing cost of coal base load resources • Regulation of carbon dioxide (CO2) emissions is gaining traction • New licensing process expected to allow cost control • New design units are smaller and less costly to construct
